To all whom it may concern:

Be it known that 1, CHARLES MILD, a citizen of the United States,residing at Mount Vernon, in the county of Knox and State of Ohio, haveinvented a new and useful Improvement in Cleaners for Steam- Condensers,of which the following isa specification.

My invention relates to improvements in cleaners or steam condensers.

The object of my invention is to provide a cleaner of this characterwhich is adapted to operate on the inner water-cooled surface of acondensing cylinder for removing any deposits which may adhere to thecylinder. The water-cooled surface of the condenser is at all times freefrom any deposits a'nd the water flowing over the same has a greatercondensing action upon the steam within the cylinder.

Another o'oiect of my invention is to provide a more simple, cheap andeffective cleaner which is readily adjusted to fit cylinders ofdifferent diameters and also provided with means for varying thepressure of the brushes and scrapers on the water-cooled surface.

In the accompanying drawings: Figure 1 is a vertical sectional view ofasteam condenser, showing my improved cleaner applied thereto; Fig. 2 isa transverse sectional view taken on the line z:c of Fig. l; and Fig.11' is an enlarged detail plan view of the brush and scraper.

Referring now to the drawings, 1 represents the condensing cylinder,which, as shown, is composed of an outer vertically disposed cylinder 2and an inner inclined cylinder 3 forming a steam condensing space 4between the same. lhe upper and lower ends of the cylinders haveconnected thereto plates 5 and 6 which close the upper and lower ends ofthe steam condensing chamber 4. The said condenser is supported upon abase 7 and is provided with a steam supply pipe 8 a short distance abovethe base. The inner inclined cyl indcr 75 at its upper end is providedwith a water supply pipe 9 end deflecting plates 10 and ll fordeflecting and spraying the water against or upon the inner face of saidcylinder. The water thereupon travels downwardly in :1 thin sheet overthe cylinder and keeps the same comparatively cool.

It has been found in condensers of this character that the innercylinder 33 soon becomes couted with a deposit from the water and the c:udcr does not readily transmit the cooling effect of the water to theinner lace oi the cylinder. In order to prevent this collection ordeposit on the inner cylinder, 1 provide a vertically disposed shaft 12rotatably supported in the center of the inner cylinder 3, the saidshaft being supported at its upper end by a transversebar l3 and itslower end by a plate 14 and is held against longi- Specification ofLetters .Estsnt.

tudinal movement. The upper end of the shaft extends a distance abovethe upper end of the cylinder and is provided with a worm gear andmeshing vvith the said worm gear 15 is a. Worm 16 which is carried onthe shed 17 of a water motor 18. The water motor may be driven throughthe medium of the water supply to the inner cylinder, thus the saidshaft is Caused to continually rotate,

The. shaft 12 at its upper and lower ends and at the center is providedwith oppositely arranged radially extending arms 19 and El) which arerigidly secured to the shaft by set-screws 2]. The outer ends of saidarms have rigidly mounted therein vertically disposed rods 22 and 23which extend parallel with the shaft. The said rods have loosely mountedthereon the arms 24 and 24 which are provided on their inner ends withsegmental plates 25 having segmental slots 26 through which passes aset-screw 27 which enters the arm 24 and whereby the arms may beadjusted in any position. The outer ends of the arms extend adjacent tothe inner face of the cylinder Ll and support the brushes 28 andscrapers '29. The scrapers and brushes bear against the inner surface ofthccylinder 3 and keeps it absolutely free of any deposit. The scraper29, as shown, is of an elongated shoot of metal having a series oftransverse slots 30 extending from one edge about three-fourths of thewidth of tho scraper. Carried by theoutcr ends of the arms 24 are bolts31 which pass through said slots and securely fasten the scrapers to thearms, the slots allowing for the inward and outward adjustment oi thesaid scrapers. From the drawings, it will be seen that the scrapers arenot made oi a single piece extending the whole length oi the cylinder,but are made in sections and the same slots 30 are used for securing thesaid sections together for hunting a continuous scraper. The brush 28 islikewise secured to the arm 24" by the bolt 31, but instead of havingslots they are provided with openings- 32 through which the bolts 31pass. These brushes need no adjustment to or fr in the cylinder 3 as theelasticity of the bristles of the brush does not require as fine anadjustment as do" the scrapers.

Having thus fully described my invention, what I claim as new and desireto secure by L tters Patent. is:

A cleaner for steam condensers comprising :1 rotary shaft. radiallyextending ui'ms curried by the said shaft, verticallydisposcdbursrigidly carried by the outer ends of said arms and parallelwith the shaft, brush and scraper c ylng members loosely mounted on thesold bars and having segmental slots at ,their inner err/s, passingthrough said slots for udjuntubl; holding said members. 'oolts passingthrough the outs ends of said members and brushes and scrapers securedthereto by the bolts.

set-screws 2.v A eleaner for steam condensers, comprising a rotary'respectively, through which they .=zi -1e secured to the said shaft,radially extending arms carried by the shaft, vertically disposed barscarried by the outer ends of the said segmental slots at their innerends, setscrews passing *through said slots for adjustnbiy holding saidmembers, bolts passing "through the outer ends of said members,

- And brushes end scrapers having openings and slots,

members and by means of which they are secured together. In testimonywhereofl i iin'we signed my name to this specification in the present-eof two subscribing witnesses.
